I want to get list of connected users in a specific channel on voiceStateUpdate with this way:

module.exports = async (client, oldState, newState) => {
  const channel = await newState.guild.channels.fetch('719030671384772609');
}

but I don't see members property when checking the collections,

  'channelid' => <ref *8> VoiceChannel {
    type: 'GUILD_VOICE',
    deleted: false,
    guild: Guild {
    },
    guildId: '',
    parentId: '',
    permissionOverwrites: PermissionOverwriteManager { channel: [Circular *8] },
    id: '',
    name: '',
    rawPosition: 2,
    rtcRegion: 'hongkong',
    bitrate: 64000,
    userLimit: 0
  },

Did I miss something here? or an alternative way?
